Similar letters of reference indicate corresponding parts.

A is the bracket. B is the horizontal or bearing-bar, upon which the vstaging-plank (seen in to the end of B.A .In using the bracket the claws or teeth penetrate the roof, as seen, and prevent slipping. D is the vertical portion of the bracket, provided with a screw-thread. E E are pointed arms attached to the screw-head F. The bracket is made adjustable as to height by means of the screw passing through the screw-head F. arms E E stand at an angle with the screw, and so as to brace the bracket laterally in each direction.

This bracket is cheap, safe, and convenient, and its advantages over anything ofthe kind in use must be obvious to all.
